+ * A few noteworthy observations:
+ * 1. This function is meant to be used in places where YT_VERIFY won't look out of place, but
+ *    it's safe to just throw an exception. Because of this, this error should not be handled by
+ *    clients in any specific way.
+ * 2. Most places where this could be used have trace_id enabled, which would make it easy for
+ *    administrators to find a correlation between an alert and an error, if a user were to report it.
+ * 3. Administrators will receive this alert, so there is no need to enrich the error with
+ *    additional information.
